Horava Lifschitz theory and Lorentz Invariance

Click For Summary
SUMMARY

Horava-Lifschitz theory modifies Lorentz invariance at high energies, suggesting potential variations in the speed of light for different photon frequencies from gamma-ray bursts. However, the actual observable effects depend on specific free parameters within the theory. These parameters influence the phenomenological outcomes, making it essential to refer to Horava's original paper for a deeper understanding of their implications.

PREREQUISITES
  • Understanding of Horava-Lifschitz gravity theory
  • Familiarity with Lorentz invariance concepts
  • Knowledge of high-energy physics

As I understand it Horava Lifschitz theory breaks lorentz invariance at high energies.
Does this mean we should see photons from gamma ray bursts leave a signal of varying speeds of light for different frequencies?

Not necessarily.
Cn you elaborate? Why not? What does it depend on?
 
Horava theory is a theory of gravity with some free parameters. The phenomenological consequences may depend on the exact values of those parameters.
 
Thanks for that , can you elaborate on the nature of these free parameters,?sorry to be a pain just trying to understand a bit better.
 
It's quite technical, so I would suggest to take a look at the Horava's paper.
